I noticed that, depending upon the value of the 'job-sheets' IPP option,
the 'number-up' option will be ignored.

In the following job (created from the control file in /var/spool/cups
using testipp), the number-up option will simply be ignored, i.e. the
printout is still one logical page on one sheet:

The call to the filter creates the following command line arg (from the
error_log file in debug mode, using the "HP DeskJet Series CUPS v1.2"
filter):

argv[5]="PageSize=A4 Resolution=300dpi MediaType=Plain InputSlot=Tray
ColorModel=CMYK job-uuid=urn:uuid:045ada08-90d2-3091-762f-abb9e0645ba7"

I hacked the application creating the IPP job (which is actually the
gtk+-2.10.6 cups print driver) to replace the "none,none" in 'job-sheets'
by simply "none".  The diff between the jobs (with "+" marking the working
version) is

and now the number-up option /is/ used as expected (i.e. two pages on one
sheet).  In the working case, the filter argv is

argv[5]="PageSize=A4 Resolution=300dpi MediaType=Plain InputSlot=Tray
number-up=2 ColorModel=CMYK
job-uuid=urn:uuid:f790972c-cf4c-3499-7bb9-c38629a1f614"

The behavior seems to be independent of the ppd used; I first saw this
using the HP Deskjet 5150 PPD from foomatic.  IMO, even /if/ the
job-sheets option with two parameters would be wrong (is it?), it should
not influence other legal options.
